When I brought this up a year ago, people told me it was the fault of
my email client, and that I should stop complaining about it.
However, if it isn’t obvious by now to everyone that this behavior
needs to stop, it never will be. It takes 1/100th of the time you
spend typing the body of your email to type the first few letters of
"maxmsp" into your To field before autocomplete takes over.

The reply-to header is a very useful piece of information that can
enables forum/list integration go smoothly (you still have issues
with quoting versus non-quoting, but if you use threading in your
email client, this is negated). Without it, it would be incredibly
difficult (you’d have to guess by the subject). To ignore it or abuse
it makes the forums and threaded email clients less useful (or worse,
unusable, as is now basically the case).

I know I sound like a whiny brat, but the abuse of reply-to literally
doubles the amount of time I have to spend parsing the Max list to
find what is interesting/helpful/etc. This is a high volume list, and
if I want to look at everything that goes through, threads can knock
five minutes off my email time each day and make it less of a hassle
as well.

see john, you name it, quoting and not quoting
is the next issue we have when 50% uf us are
using the forum and 50% reading mails.

back in the days noone ever used the archieves
for other purposes than searching, and proper
threads were not required for that.
now many people use the archieves (=forum), because
you can also reply here now.
